The image below is an example of a Emergency Egress Map. They are posted in classrooms, many offices and some public spaces.
The Emergency Egress Plan identifies the area's emergency exits, areas of rescue assistance, AEDs (automated external defibrillators), shelter-in-place locations for severe weather and evacuation rally point locations.
Emergency Egress Maps are not available online. It's important to study the Emergency Egress Map posted in your area BEFORE an emergency.
